Crushed Exhaust

[Snap-on]

Hey peoples,
My vp has some of a stock exhaust (rear resi removed). Where it goes over the panhard rod, the pipe is crushed/dented. Is this a factory thing or has something dented it? Thanks

Its probably factory as they just bend the pipe in a press instead of using mandrel bends. If you are happy with the stock exhaust but want a little more flow you could probably ask a exhaust shop to weld in a mandrel bend for you.

it is on the outside of the bend, if you know what i mean. Not just a reduced diameter effect like a pipe bender

Could have bottomed out at some point or had the exhaust get pushed up some how. Either way it would be restricting flow by what you have described.

The stock exhaust has a flattened section there to clear the body brace just above it.

Here is a pic I took -

Still reckon it is factory?

Yep, Holden is more dodgy then I am.

Reckon this creates a whistling sound with high rpm?

Definately not a standard dent, get it removed.......2.5inch exhaust should do it Whistleing sound at high rpm = commodore, heard so many do it.

I've seenheaps of standard systems dented the exact same way.

Whistling noise is normal. Its generally the motor sucking in air.
